The design principles Tanenbaum applied to MINIX had influenced the design decisions Linus Torvalds applied in the creation of the Linux kernel. Torvalds used and appreciated MINIX, but his design was different from the MINIX architecture in significant ways, most notably by employing a monolithic kernel instead of a microkernel. This was famously disapproved by Tanenbaum in the Tanenbaum-Torvalds debate. (Tanenbaum explained again his rationale for using a microkernel in May 2006.)

These accusations were refused by almost everyone - in particular by Andrew Tanenbaum, who strongly felt that Kenneth Brown was very wrong and published a long rebuttal on his own personal website.[2][3]
